To all whom it may concern.'

Be it known that we, FELIX No'rz, a citizen j ol' the 'United States, residing at Chicago, in 3 of the machine.

the county of @ook and State of Illinois, Intermediate between the links 16 and 17 and nnoires ROYAN, a subject of the King ,l extends the shifting lever 21 that is pivoted y oted as at 18 and 19 to a support or pedestal 20 that is bolted to and rises from the base Great Britain, residing at Chicago, in the as at 22 to the top of the support or pedestal county of 20 and the extreme rear end of the ever 21 is pivoted as at 23 to the bar 14. The lever 21 is shown as extending forwardly to the front of the machine so that the operator may from such point conveniently shift the belt 12 from the fast to the loose pulley, and I vice versa. If desired, means may be einployed for holding the lever 21 in its different positions, but this is not regarded as essential to the invention. As the operating lever 21 is shifted, the bar 14 that carries the fork 13 will, as it is moved, remain substantially parallel to the shaft 7 whereon the ulleys 1() and 11 are mounted, this parallelism oi' the bar 14 being secured by the parallel links ticularly pointed out iii the claims at the end connecting` it with the pedestal or support of this specii'ication. 20. Manifestly, the number and length of Figure 1 is a view in vertical section online l the links connecting the bar 14 to the pedes- 1-1 of Fig. 2. Fig. 2 is a plan view, parts l tal or support is not essential, and a iroper being` broken away for better illustration. f movement of the bar 14 could be e li'ected, 3 designates the base of the machine from even if one of the links 16 or 17 were omitted, which rise standards L and 5 whereon are t in which case the rear portion of the operatniountcd the shafts 6 and 7, these shafts being` lever 21 would perform the function of ing shown as connected together by gear such link. wheel 8 and pinion On the shaft 7 are It is obvious that the precise details of conmounted the xed and loose pulleys 10 and struction above set out may be varied with- 11 of any suitable size and shape, and over out departing,I from the scope of the inventhe fixed pulley 10 extends a driving belt 12. tion, these details depending upon the posi- 'ihe improved belt shifting mechanism I tion in which the pulleys 10 and .11 are placed i and in which the belt 12 is run.

As shown, also, |`pivotally connected to said fork carrier and the lower ends of the fork 13 pass through the to said support and a shifting fork connected ends of links 16 and 17 which are thus pivotl to said fork carrier at opposite sides of said ally connected to the bar 14.
